Intraretinal Cystoid Changes After Vitrectomy With Membrane Peeling

Completed

• Conditions: Macular Edema, Cystoid
• Interventions: Device: optical coherence tomography (OCT)

• Registration Number: NCT04472039
• Lead Sponsor: Vienna Institute for Research in Ocular Surgery

Brief Summary

Aim of the study is to assess the rate of postoperative intraretinal cystoid changes after pars plana vitrectomy with membrane peeling and peribulbar application of triamcinolone acetonide and to examine possible risk factors for postoperative intraretinal cystoid changes.

Detailed Description

Epiretinal membranes (ERM) are disorders leading to vision loss and metamorphopsia. Vitrectomy with membrane peeling has developed to be the gold-standard in treatment of ERM. Nevertheless, there are about 10% of patients having intraretinal cystoid changes after surgery with potential for disturbance of visual acuity. The aim of the study is to assess the rate of postoperative intraretinal cystoid changes after pars plana vitrectomy with membrane peeling and peribulbar application of triamcinolone acetonide and to examine possible risk factors for postoperative intraretinal cystoid changes.
